Objective:
To explore the association between dietary inflammatory index (DII) and elevated blood pressure among primary school students, and to analyze the mediating role of body mass index (BMI) in this association, so as to provide a scientific basis for the early prevention of childhood hypertension and dietary guidance.
Methods:
Research conducted based on the Ma anshan Child Growth Cohort in Anhui Province. From April to June 2024, 4 057 primary school students were selected as study subjects using a multi stage cluster sampling method. Dietary information was collected via Semi quantitative Food Frequency Questionnaire to calculate the DII score. BMI was obtained by measuring students height and weight. Elevated blood pressure was defined based on the Blood Pressure Reference Standards for Children Aged 3-17 Years. Logistic regression was used to analyze the association between DII scores and the risk of elevated blood pressure, and the Bootstrap method was employed to test for mediating effects.
Results:
The detection rate of elevated blood pressure among primary school students was 10.1% (408 cases). Multivariate Logistic regression analysis showed that, after adjusting for covariates such as gender and age, for each standard deviation increase in the DII score ( s =1.94), the risk of elevated blood pressure increased by 15% ( OR =1.15, 95% CI =1.04- 1.28 , P <0.05). Compared with the lowest quartile group of DII scores ( Q 1), students in the highest quartile group ( Q 4) had a 1.31-fold higher risk of elevated blood pressure ( OR =1.31, 95% CI =1.00-1.76, P <0.05). Restricted cubic spline results indicated a linear dose response relationship between DII scores and the risk of elevated blood pressure( P nonlinear =0.13). The mediation analysis revealed that BMI played a partial mediating role in the association between DII scores and elevated blood pressure. The mediation effect value was 0.06 (95% CI =0.04-0.08), accounting for 44.64% of the total effect.
Conclusions
DII scores are associated with elevated blood pressure among primary school students in Ma anshan City, and BMI plays a partial mediating role in this association. Promoting an anti inflammatory dietary pattern and weight control in early childhood should be emphasized to reduce the incidence of hypertension among primary school students.

Background Lead is a typical persistent environmental pollutant that can accumulate in bones for decades. During pregnancy, alterations in calcium metabolism promote the mobilization of bone lead, resulting in secondary exposure; however, the mechanisms by which pregnancy-associated bone lead mobilization affects maternal renal function remain unclear. Objective To investigate the role of mitochondrial dysfunction in pregnancy-related bone lead mobilization-induced renal injury. Methods Newly weaned female Wistar rats were randomly assigned to a control or a lead-exposed group administered either 0.05% sodium acetate or 0.05% lead acetate in drinking water. Following a 4-week lead exposure and a 4-week washout period, the females were co-housed with healthy age-matched males for mating. Rats were sacrificed at early (gestational day 3) and late (gestational day 17) pregnancystages, respectively. Renal histopathology was assessed using hematoxylin and eosin staining staining. Mitochondria-related indicators, including oxidative stress, inflammatory responses, and energy metabolism, were measured. Differential metabolites were identified using serum metabolomics. Results Renal injury in the lead-exposed pregnant rats progressed in a time-dependent manner, characterized by degeneration of proximal tubular epithelial cells, glomerular hyaline changes, and interstitial inflammatory cell infiltration. Repeated measures ANOVA indicated a significant interaction between the treatment factor (lead exposure) and the temporal factor (gestational stage) on renal injury (P<0.001). Further analysis of mitochondrial function-related indicators in late-pregnancy renal tissue revealed that the lead exposure group exhibited significantly increased levels of malondialdehyde (MDA) and reactive oxygen species (ROS) (P<0.05), accompanied by a reduction in superoxide dismutase (SOD) and reduced glutathione (GSH) activities (P<0.05); regarding inflammatory markers, levels of interleukin-18 (IL-18) and interleukin-1β (IL-1β) were elevated (P<0.01), whereas interleukin-33 (IL-33) was decreased in the lead-exposed group (P<0.05); energy metabolism-related indicators, including adenosine triphosphate (ATP) level, Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities, and mitochondrial respiratory chain complexes I, III, and V activities, were significantly reduced (P<0.05) in the lead-exposed gorup. The typical differential metabolite N-methylisoleucine, identified through serum metabolomics analysis, was negatively correlated with blood lead levels, kidney injury scores, and IL-1β, while positively correlated with catalase (CAT) activity and Ca2+-Mg2+-ATPase. Conclusions Mitochondrial dysfunction may play a critical role in renal injury induced by bone lead mobilization during late gestation.

Genetically modified pigs for welfare assurance is crucial for conducting xenotransplantation. However, traditional experimental animal ethics principles cannot address the social benefits issues brought about by xenotransplantation, and there is a lack of ethical justification for the assurance of experimental animal welfare. Degrazia and Bechtel proposed six principles for the welfare of experimental animals: the principle of no alternative methods, the principle of expected net benefits, the principle of adequate defense of harm, the principle of no harm without necessity, the principle of basic needs and the principle of harm limit. This paper conducts an ethical-level argumentation on the six principles for the welfare of genetically modified pigs in xenotransplantation, and points out that these six principles are of great significance in closely integrating the social benefits of xenotransplantation with the welfare of genetically modified pigs, emphasizing the moral status of genetically modified pigs, and providing standards for the ethical review of the welfare of genetically modified pigs.

Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

OBJECTIVE To investigate the effects and mechanism of Yigan huayu formula in alleviating liver fibrosis in mice. METHODS Mice were randomly divided into blank group (normal saline), model group (normal saline), Yigan huayu formula low- and high-dose groups (28.98, 57.96 g/kg, calculated by crude drug), with 8 mice in each group. Except for the blank group, the liver fibrosis model was induced by intraperitoneal injection of 15%CCl 4 -olive oil solution. From the third week, the mice received the medicine/normal saline intragastrically, once a day, for 4 consecutive weeks. After the last medication, liver indexes were calculated, the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum, as well as the hydroxyproline (HYP) content in liver tissue, were measured. Liver histopathology was evaluated. Differentially expressed proteins (DEPs) in liver tissue were analyzed based on proteomics, followed by bioinfo rmatics analysis. The expressions of core DEPs were validated using Western blot (WB) and immunohistochemistry (IHC) methods. RESULTS Compared with the blank group, the model group showed significantly elevated liver indexes, serum activities of ALT and AST, and hepatic HYP content ( P <0.05), along with obvious pathological damage and collagen deposition. Compared with the model group, the above indexes of mice in the Yigan huayu formula high-dose group were decreased significantly ( P <0.05), with marked improvement in liver pathological damage and collagen deposition. Proteomics identified 210 DEPs between the model group and Yigan huayu formula high-dose group. DEPs were significantly enriched in extracellular matrix (ECM)-receptor interaction and lipid metabolism pathways. WB and IHC confirmed that Yigan huayu formula could significantly inhibit the abnormally elevated expressions of collagen type Ⅳ alpha1 chain (COL4A1), secreted protein acidic and rich in cysteine (SPARC), vitronectin (VTN) and laminin subunit alpha5 (LAMA5) in liver tissue of mice ( P <0.05). CONCLUSIONS Yigan huayu formula may exert anti-hepatic fibrosis effects by inhibiting the expressions of proteins such as COL4A1, LAMA5, SPARC, and VTN, thereby blocking the ECM-receptor interaction signaling pathway, and subsequently suppressing excessive ECM deposition and basement membrane remodeling.

Objective To explore the non-invasive diagnostic criteria of magnetocardiography (MCG) for coronary microvascular dysfunction (CMVD), and its value in dynamically assessing drug treatment for CMVD. Methods Patients who presented with chest tightness or chest pain at Zhongshan Hospital, Fudan University from September 2024 to March 2025 were consecutively enrolled, and all of whom had non-obstructive coronary arteries on angiography. Using the coronary angiography-derived index of microcirculatory resistance (caIMR) as the gold standard, patients were divided into a normal microcirculation group (caIMR≤40 U) and a CMVD group (caIMR>40 U). MCG testing was performed using a domestic device (MD-U041001, Mind Medical). Patients in the CMVD group received adenosine treatment and underwent repeat MCG after medication. Differences in MCG parameters between the two groups were analyzed, and a diagnostic model was established. The value of the diagnostic model was analyzed using receiver operating characteristic (ROC) curves. Results A total of 311 patients were included, with 135 in the normal microcirculation group and 176 in the CMVD group. The CMVD group had a significantly higher proportion of males (61.9% vs 47.4%, P=0.012), and lower high-density lipoprotein cholesterol (HDL-C) levels ([1.16±0.31] mmol/L vs [1.24±0.29] mmol/L, P=0.029) than the normal group. Eleven MCG parameters showed significant differences between the two groups (P<0.05), among which increased values of mfm_QR_epav, mfm_RS_epmse, space_zeroRTrot, as well as decreased value of mfm_QR_v1 were independent predictors of CMVD. The diagnostic model based on these 11 MCG parameters yielded an area under the curve (AUC) of 0.688 (95%CI 0.629-0.747). The integrated diagnostic model combining clinical risk factors (male, smoking history, HDL-C) with MCG parameters had an AUC of 0.701 (95%CI 0.643-0.759). After adenosine treatment, patients in the CMVD group showed significant decreases in mfm_QR_epav (P=0.010), mfm_RS_sad (P=0.013), and mfm_RS_epmse (P=0.046). Conclusions The model based on MCG parameters demonstrates good diagnostic ability for CMVD; dynamic changes in MCG parameters following adenosine intervention may serve as potential objective indicators for evaluating microcirculatory treatment efficacy.

ObjectiveTo explore the changes in color, odor and chemical components during wine-processing of Chuanxiong Rhizoma(CR), identify differential markers, and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis(PLS-DA), principal component analysis(PCA), discriminant factor analysis(DFA) and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models, and differential components were screened out based on variable importance in the projection(VIP) value1. Then, high performance liquid chromatography(HPLC) was employed to detect the content changes of four components(ferulic acid, senkyunolide I, senkyunolide A and ligustilide) during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L*(brightness value), a*(red-green value) and b*(yellow-blue value). Based on chromaticity differences, the color reference ranges were established for moderately processed CR, including L* of 46.75-48.24, a* of 5.37-6.07 and b* of 20.32-21.70. In odor analysis, DFA revealed significant differences among processing stages, and 11 odor markers were identified, with four differential markers(4-hydroxy-3-butylphthalide, isopropyl butyrate, L-limonene and 1-methoxyhexane) based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection, with discrimination accuracy rates of 92.4% and 93.272% for color and odor, respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages, and four differential components were screened out, providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

ObjectiveTo investigate the possible mechanism of Jishe Qushi Capsule (脊蛇祛湿胶囊, JQC) in treating rheumatoid arthritis (RA) from the perspective of macrophage polarization mediated by neutrophil extracellular traps (NETs). MethodsTwenty-four female SD rats were randomly divided into four groups, blank control group, model group, JQC group, and peptidylarginine deiminase 4 (PAD4) inhibitor group with 6 rats in each group. All groups but the blank control group were subjected to the induction of collagen-induced arthritis (CIA). After successful model establishment, rats in the JQC group received intragastric administration of JQC 1.47 g/kg daily; rats in the PAD4 inhibitor group received intraperitoneal injections of the PAD4 inhibitor 4 mg/kg weekly. Rats in the blank, model, and PAD4 inhibitor groups received 2 ml of pure water daily by gavage. All treatments lasted 4 weeks. Joint lesions of each group were assessed on day 7, 14, 21, 28, and 35 after model establishment, and arthritis index (AI) scores were recorded. At 24 h after the final administration, histopathology of knee joints, including HE staining, safranin O-fast green staining, and TRAP staining, was performed. Flow cytometry was used to detect the counts of M1 and M2 macrophages in peripheral blood. ELISA was used to determine serum levels of TRACP, NETs, TNF-α, IL-1β, and iNOS. Western Blotting and qRT-PCR were used to measure MPO, NE, RANKL, OPG, and p65 protein and mRNA expression in knee cartilage tissue. ResultsCompared with the blank control group, the model group showed increased AI scores (P<0.05), marked synovial inflammatory infiltration, angiogenesis, and bone-cartilage destruction, increased TRAP-positive osteoclasts, increased M1 macrophages and decreased M2 macrophages, elevated serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), elevated MPO, NE, RANKL, and p65 protein/mRNA expression and decreased OPG protein/mRNA expression in knee cartilage tissue (P<0.05). Compared with the model group, the JQC group exhibited improved synovial inflammation, angiogenesis, and bone-cartilage damage, reduced AI scores on day 21, 28, and 35, decreased osteoclast counts, decreased M1 macrophages and increased M2 macrophages, reduced serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), decreased MPO, NE, RANKL, and p65 protein/mRNA expression and increased OPG expression (P<0.05). Compared with the PAD4 inhibitor group, the JQC group showed significantly lower AI scores, reduced M1 macrophages, increased M2 macrophages (P<0.05), reduced serum TRACP, TNF-α, IL-1β, and iNOS, decreased MPO, RANKL, and p65 expression, and increased OPG levels (P<0.05). ConclusionThe therapeutic mechanism of JQC for RA may involve inhibition of NETs formation, downregulation of the RANKL/NF-κB signaling pathway, and regulation of macrophage M1/M2 polarization imbalance, thereby suppressing osteoclastogenesis and inflammatory bone destruction.
